Hello, I am carrying out a flow simulation on a wheel, left most setting on default, but with si units, flow 20m/s direction X, externatal, laminar flow, using wizard, run the project, but its been running now for 4 hours and its telling me its got another 5 hours to go, I must be doing something wrong, I hope it does not take this length of time otherwise I will only have time to run a few different projects, please help, thanks
